Bitcoin isn't anonymous. The entire history of every transaction between every wallet is visible. This means if someone knows your wallet ID (i.e. you bought something from them and shipped it) they know exactly how much bitcoin you have in that wallet. Some people try to be anonymous on it, but as some of the drug dealers on Wall Street Market found out, that's pretty hard to do. Law enforcement was able to track down some of them by tracing their bitcoin transactions.
